pfstools is a set of command line programs (and one GUI program) for reading, writing, manipulating, and viewing high-dynamic range (HDR) images and video frames. All programs in the package exchange data using Unix pipes and a simple generic HDR image format (pfs). It is meant to be similar to the netpbm package for low-dynamic range images. Note that pfs in not just another format for storing HDR images. It is more an attempt to integrate the existing HDR image formats by providing a simple data format that can be used to exchange data between applications.
LayoutEditor is an IC/MEMS layout editor. It features all angle elements, a font generator, macros, Boolean operations, drc, netlist-driven layout, LVS, and cross-platform compatibility. Supported formats include Calma GDSII, OASIS (Open Artwork System Interchange Standard), DXF, CIF (Caltech Intermediate Form), Gerber, DEF/LEF, and many others.
UProxy is a proxy for UDP protocols. UProxy was initially designed to allow users to play Unreal Tournament matches over the Internet on computers sharing a dial up connection. It could also be used by any client-server application that uses the UDP protocol and doesn't require clients to bind a fixed port. UProxy should run under Windows, Linux, or any OS which supports BSD sockets.
GNU libsigsegv is a library for handling page faults. A page fault occurs when a program tries to access a region of memory that is currently not available. Catching and handling a page fault is a useful technique for implementing garbage collectors, stack overflow handlers, persistent databases, and distributed shared memory.
Khayyam is a program for composing 3D scenes for rendering (similar to Poser and DAZ Studio). It can import character and scene models from many model formats (Poser, MD5, BSP, OBJ, 3DS, Collada, and formats used in most Illusion games). There is support for basic object placement, scaling, posing skeletal characters, and lighting. Scenes can be exported in POV-Ray format for rendering. Khayyam is implemented as a shell program using many libraries from the Floyd and Sodipodi projects.
